Class JsEngineStub
- JsEngine, Remote, RemoteService
public class JsEngineStub
Object | eval(String docname, String fnOrScript, int lineno) - Allow the debugger to evaluate an expression
within the current context.
|
JsContext | getContext(int depth) - Returns the JsContext at a certain depth.
|
int | getContextCount() - Returns the count of JsContext on the current stack.
|
JsCallbacks | getDebugger() - Return the current debugger.
|
JsObject | getGlobalObject() - Any execution in JavaScript happen with respect to a
global object, sort of the top-level name space for
properties.
|
String | getThread() - Returns name of the thread currently running in the engine
|
String | getThreadGroup() - Returns name of the ThreadGroup of the thread currently running in the engine
|
JsObject | getUndefinedValue() - As per ECMA specification, each JavaScript execution
defines a unique object for the undefined value.
|
boolean | isSuspended()
|
boolean | poll() - Allows the client debugger to poll the connection.
|
void | run() - Stepping commands:
run: resume execution until it finishes or a breakpoint is hit.

eval
public Object eval(String docname,
String fnOrScript,
int lineno)
throws RemoteException
Allow the debugger to evaluate an expression
within the current context.
- eval in interface JsEngine
getContext
public JsContext getContext(int depth)
throws RemoteException
Returns the JsContext at a certain depth.
Depth zero is the top of the stack, that is,
the inner execution context.
This is a valid call only if the engine is stopped
in a callback to the debugger (breakpoint or stepping
completed).
- getContext in interface JsEngine
getContextCount
public int getContextCount()
throws RemoteException
Returns the count of JsContext on the current stack.
This is a valid call only if the engine is stopped
in a callback to the debugger (breakpoint or stepping
completed).
- getContextCount in interface JsEngine
getDebugger
public JsCallbacks getDebugger()
throws RemoteException
Return the current debugger.
- getDebugger in interface JsEngine
- the debugger, or null if none is attached.
getGlobalObject
public JsObject getGlobalObject()
throws RemoteException
Any execution in JavaScript happen with respect to a
global object, sort of the top-level name space for
properties. This is global object return by this call.
- getGlobalObject in interface JsEngine
getThread
public String getThread()
throws RemoteException
Returns name of the thread currently running in the engine
- getThread in interface JsEngine
getThreadGroup
public String getThreadGroup()
throws RemoteException
Returns name of the ThreadGroup of the thread currently running in the engine
- getThreadGroup in interface JsEngine
getUndefinedValue
public JsObject getUndefinedValue()
throws RemoteException
As per ECMA specification, each JavaScript execution
defines a unique object for the undefined value.
- getUndefinedValue in interface JsEngine
poll
public boolean poll()
throws RemoteException
Allows the client debugger to poll the connection.
- poll in interface JsEngine
run
public void run()
throws RemoteException
Stepping commands:
run: resume execution until it finishes or a breakpoint is hit.
stepIn: steps to the next statement, considering callee's statement if any.
stepOut: steps until the current JsContext exits.
stepOver: steps to the next statement within the same JsContext.
- run in interface JsEngine
setDebugger
public void setDebugger(JsCallbacks debugger)
throws RemoteException
Set the associated debugger.
- setDebugger in interface JsEngine
debugger
- the debugger to be used on callbacks from
the engine.
stepIn
public void stepIn()
throws RemoteException
- stepIn in interface JsEngine
stepOut
public void stepOut()
throws RemoteException
- stepOut in interface JsEngine
stepOver
public void stepOver()
throws RemoteException
- stepOver in interface JsEngine
